The Triplespec and IRTF spectra were reduced using the IDL package spextool [1]}, and were flux calibrated and corrected for telluric absorption with standard star observations using xtellcor [2]}. The UKIRT spectrum of HD 137613 was reduced in a standard manner using the Figaro software package for flatfielding, removal of the effects of cosmic ray hits, spectral and spatial rectification of the spectral images, wavelength calibration using an argon lamp, and ratioing by the spectrum of a standard star. The Gemini spectra were reduced similarly, but used a combination of IRAF and Figaro as described in [3]}.
